This paper addresses the problem of full body articulated human motion tracking from multi-view video data recorded in a laboratory environment. The problem is formulated as a high dimensional (31-dimensional) non-linear optimization problem. In recent years, metaheuristics such as Particle Swarm Optimization (PSO), Ant Colony Optimization (ACO), Artificial Immune System (AIS), Firefly Algorithm (FA) are applied to complex non-linear optimization problems. These population based evolutionary algorithms have diversified search capabilities and are computationally robust and efficient. One such recently proposed metaheuristic, Bat Algorithm (BA), is employed in this work for full human body pose estimation. The performance of BA is compared with Particle Filter (PF), Annealed Particle Filter (APF) and PSO using a standard data set. The qualitative and the quantitative evaluation of the performance of full body human tracking demonstrates that BA performs better then PF, APF and PSO.
